What is jet lag?

Jet lag recovery time

How long it takes to recover from jet lag depends on the number of time zones crossed.

Distance travelled

Flying across just one or two time zones will not make a huge difference to your body. Yes, you may be tired or wakeful at odd times, but this will be down to fatigue, travel discomfort and possibly stress-related issues.

If you travel across three or more time zones you’re more likely to experience true jet lag. The further you travel, the stronger and more debilitating those jet lag symptoms will be.

Direction of travel

North to south / south to north

Flying from north to south (or vice versa) will produce no noticeable jet lag effects as the time of day will remain roughly the same as your departure point, regardless of the length of the flight. Any symptoms should disappear after a good night’s sleep.

Your body finds it easier to adjust to ‘forcibly’ lengthening the day as opposed to shortening it. It is easier to stay up a bit later at night than it is to go to bed earlier than your body expects.

West to east

Travelling from west to east is said to be the most difficult jet lag to deal with. This is because you ‘lose’ time. You’d be going to bed ‘too early’ according to you internal body clock.

East to west

If you travel from east to west, you ‘gain’ time, which makes it easier to adjust. You may wake up a bit earlier than you’d like, but all in all, you should find the effects aren’t too incapacitating.

Duration of jet lag symptoms

Your body generally takes one day to recover per one or two time zones. So if your flight crossed eight time zones, you should readjust in about a four to eight days. Or thereabouts…

If you travel west to east it should take in days, approximately two-thirds the number of time zones crossed.

If you travel east to west it should take in days, approximately half the number of time zones crossed.

Got that?!

Disclaimer…

Everyone experiences jet lag differently; some are seemingly unaffected while others are very susceptible and have severe symptoms that last for ages.

There’s a running joke in our family that my husband can get jet lag from a relatively short train journey!
